Nagios Support Forum

Hi Experts,

We have Nagios 5.6.10 installed in our environment. We have some Windows 2000 and Windows 2003 servers to be monitored by Nagios XI.
While adding these servers using WMI method, we are getting the "timeout error":
WMI Error Output:

UNKNOWN - Plugin Timed out (15 sec). There are multiple possible reasons for this, some of them include - The host 10.10.193.161 might just be really busy, it might not even be running Windows.

Does Nagios XI support monitoring of Windows 2000 and Windows 2003 servers.
We have the necessary Firewall communication enabled
Nagios to remote nodes : TCP 135 and TCP 445, ICMP enabled
Remote nodes to Nagios : DCOM range of port(1024 to 65535) is enabled.
The service account which is used to connect to remote nodes from nagios has local admin privileges on the servers.

Please help with your valuable inputs.

Hi @vishal313,

That's a good question. Are you using the check_wmi_plus plugin? Looking over the help output, it does look like some checks will only work on certain versions, run the following command for more information and compare to your check command. Once that is confirmed, then try increasing the timeout value to 30 or 60 seconds and let me know if you get a valid check result back. If not please, post the full check command to the thread. Thanks, Benjamin

-t TIMEOUT
specify the number of seconds before the plugin will timeout. Some WMI queries take longer than others and network links with high latency may also require you to increase this from the default value of 15

Thank you for the response benjaminsmith.
I picked one of the Windows servers which fulfills the compatibility requirements and increased the timeout to 120 from 15..30..45..60..120.
But could not succeed. The connection is still timing out.
I could login to the Windows server using RDP with the same username and password.
Not able to close in for what else could be wrong.
The local firewall on the remote server is also Off.

Hi,

Appreciate the info update. It looks like this is not a timeout issue, but most likely an issue with the WMI service or the user account setup. We've have a helpful guide to setting up WMI checks, follow the steps to make sure you have a user account with sufficient privileges?
